Why Build an ADU

Sacramento's smartest home investment

California law has made ADUs easier to build than ever. Sacramento homeowners are adding rental income, housing for family, and significant property value - all without moving. The average Sacramento ADU adds $100K–$200K in property value while generating $1,200–$2,500/month in rental income.

FAQ

Common ADU questions

How much does an ADU cost in Sacramento?
ADU costs in Sacramento typically range from $150,000 to $350,000+ depending on size, finishes, site conditions, and whether it's attached or detached. We provide detailed estimates after a site assessment - no ballpark guessing.
Do I need a permit for an ADU in Sacramento?
Yes. Sacramento requires building permits for all ADUs. California state law (AB 68, SB 13, AB 881) has streamlined the process significantly - cities cannot impose many of the old barriers. We handle the full permitting process.
How long does it take to build an ADU?
Permitting typically takes 4-8 weeks in Sacramento. Construction runs 4-8 months depending on size and complexity. From first call to move-in, expect 6-10 months total.
Can I build an ADU on any residential lot in Sacramento?
Under current California law, most single-family and multi-family residential lots are eligible for at least one ADU. Lot size minimums have been largely eliminated. We'll assess your specific property and confirm eligibility before you commit.
What's the difference between an attached and detached ADU?
Attached ADUs share a wall with your main house - like converting a garage or adding onto an existing structure. Detached ADUs are standalone buildings in your yard. Both are fully permitted, self-contained living spaces with their own kitchen, bathroom, and entrance.
Can I rent out my ADU?
Yes. California law explicitly allows ADU rentals. Many homeowners build ADUs for rental income, aging parents, or adult children. Sacramento's rental market makes ADUs a strong investment - typical rental income ranges from $1,200 to $2,500/month depending on size and location.
